This is a real thing! In a ground breaking exercise psychology students carefully analysed the personality of their colleagues using the science of cake.

Some were neurotic, obsessive sorts who had to place every element precisely into the right position. Some were slapdash and carefree (stable extraverts). Some attacked the job with gusto and verve (extraverts all). Some were creative and artistic (feeling - perceivers). And one was Grace. There was only one Grace.
